* Test specification for test_hamming_weight
|
|
*
|
|
* Description: Test the hamming weight implementation.
|
|
*
|
|
* Test Type: Feature
|
|
*
|
|
* Targets: nvgpu_posix_hweight8, nvgpu_posix_hweight16,
|
|
* nvgpu_posix_hweight32, nvgpu_posix_hweight64
|
|
*
|
|
* Inputs: None
|
|
*
|
|
* Steps:
|
|
* 1) Call nvgpu_posix_hweight8 in loop with only the loop index bit position
|
|
* set.
|
|
* 2) Return FAIL if the return value from nvgpu_posix_hweight8 is not equal
|
|
* to 1 in any of the iterations.
|
|
* 3) Repeat steps 1 and 2 for nvgpu_posix_hweight16, nvgpu_posix_hweight32
|
|
* and nvgpu_posix_hweight64.
|
|
* 4) Call nvgpu_posix_hweight8 with input parameter set as 0.
|
|
* 5) Return FAIL if the return value from nvgpu_posix_hweight8 is not equal
|
|
* to 0.
|
|
* 6) Call nvgpu_posix_hweight8 with input parameter set to maximum value.
|
|
* 7) Return FAIL if the return value from nvgpu_posix_hweight8 is not equal
|
|
* to the number of bits in the input parameter.
|
|
* 8) Repeat steps 4,5,6 and 7 for nvgpu_posix_hweight16, nvgpu_posix_hweight32
|
|
* and nvgpu_posix_hweight64.
|
|
*
|
|
* Output:
|
|
* The test returns PASS if all the hamming weight function invocations return
|
|
* the expected value. Otherwise the test returns FAIL.

/**
|
|
* Test specification for test_be32tocpu
|
|
*
|
|
* Description: Test the endian conversion implementation.
|
|
*
|
|
* Test Type: Feature
|
|
*
|
|
* Targets: be32_to_cpu
|
|
*
|
|
* Inputs: None
|
|
*
|
|
* Steps:
|
|
* 1) Invoke function be32_to_cpu with a fixed pattern as input.
|
|
* 2) Check if the machine is little endian.
|
|
* 3) If the machine is little endian, confirm that the return value from
|
|
* be32_to_cpu is equal to the little endian order of the pattern, else
|
|
* return FAIL.
|
|
* 3) EXPECT_BUG is also tested to make sure that BUG is not called where it is
|
|
* not expected.
|
|
*
|
|
* Output:
|
|
* The test returns PASS if BUG is called as expected based on the parameters
|
|
* passed and EXPECT_BUG handles it accordingly.
|
|
* The test returns FAIL if either BUG is not called as expected or if
|
|
* EXPECT_BUG indicates that a BUG call was made which was not requested by
|
|
* the test.
